if you are describing the blower fans pushes air but no hot air...check for a low coolant level. when its low it won't put out heat until the engine is moving the water pump faster; providing more coolant flow thru the heater core. If the level is low...you have a leak. have the cooling system pressure tested. maybe the waterpump is leaking.
if the level is ok...maybe the heater core is plugged due to lack of cooling system fluid changes.
